Peptides based on the complementarity-determining regions of a pathogenic autoantibody mitigate lupus manifestations of (NZB x NZW)F1 mice via active suppression.

abstract：:Recent data suggest that initiation of signal transduction via type 1 Fc epsilon receptor (Fc epsilon RI) and other immunoreceptors is spatially constrained to lipid rafts. In order to better understand the complexity and function of these structures, we prepared mAb against lipid rafts from the rat basophilic leukemi...
